Clinical outcome of microsurgical free flap procedures in Lagos, Nigeria

Abstract

Background: Reconstruction of complex defects following radical tumour excision and post-traumatic defects has been made possible with the use of microsurgical free tissue transfer. It is associated with less donor site morbidity and hence and good surgical outcome in the reconstructed area. It is a routine procedure in the developed countries, however it is gradually evolving in the developing nations. Method: The records of all patients who had free flap reconstruction of their defects were retrieved from the unit database. The demographic characteristics, indications for surgery, choice of flap and the complications were documented. The data were analysed using appropriate statistical tools. Results: Free flaps represent 1.7% of all major flap surgeries performed. Among these patients, those between the ages of 21 and 30 years had highest number of free flaps accounting for 26% of the study population. Anterolateral thigh flap (ALT) was the most common donor flap. Venous compromise was more common among patients who developed complications. Conclusion: Despite many challenges facing successful microvascular surgery in the developing nation, formation of dedicated team and institutional support will improve the outcome of these procedures.
